- An engine overheats in traffic but is fine when driving: Technician A says a faulty thermostat may be the cause. Technician B says the fan clutch could be the cause. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardTrue or False: Pressures below atmospheric pressure cannot be detected.arrow_forwardWhile checking the condition of a cars ATF: Technician A says that if the fluid has a dark brownish or blackish color and/or a burned odor, the fluid has been overheated. Technician B says that if the fluid has a milky color, this indicates that engine coolant has been leaking into the transrnissions cooler. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- Which of the following is false? The air bag igniter assembly is a spark plug-type device with two pins that current must jump across. The air bag igniter assembly creates a spark that ignites a canister of gas generating zerconic potassium perchlorate. The air bag igniter assembly is housed in the module assembly. None of the above.arrow_forwardTechnician A labels or marks all electrical wires before disconnecting them. Technician B labels or marks all vacuum hoses and verities the connections to the underhood decal before disconnecting them. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardThe coolant temperature gauge stays low (cold) after die engine has been started and ran until the engine is hot Technician A says that the wires to the sending unit may be shorted together. Technician B says that the sending unit may be electrically open. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- An overheating vehicle is being discussed. Technician A states that the vehicle may be overheating becuase the heater control valve is stuck closed. Technician B states that the vehicle may be overheating because the PCM in not energizing the cooling fan relay. Who is correct?arrow_forwardTechnician A says that the presence of oil around a fitting of an air-conditioning line may indicate an oil leak but not a refrigerant leak. Technician B says that using an electronic leak detector is the best way to find the source of a refrigerant leak. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardA vehicle has had several radiator replacements, and each time there has been pinhole leaks in the aluminum. Technician A states that the engine coolant may need to be exchanged more often. Technician B states that the engine grounds should be inspected closely since this could be the cause. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor Barrow_forward
- Technician A feels up and down the face or along the return bends of the condenser for a temperature change and says that there should be a gradual change from hot to warm from the bottom to the top. Technician B says that a restriction in the condenser will be evident by a sudden change in temperature. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhich of the following is not a true statement about thermostats? Faulty thermostats are often the cause of air pockets in the coolant passages. They can also cause an increase in fuel consumption and poor engine performance. If the thermostat is stuck open, the coolant may not reach the desired temperature because it is cooled before it gets hot If a thermostat is stuck closed, coolant will not flow between the engine and radiator and the engine will quickly overheatarrow_forwardThe A/C compressor cycles rapidly, and air coming from the vents is only slightly cool. Technician A says the problem could be a low refrigerant charge. Technician B says the problem could be a defective thermostatic switch. Who is right?
